What is the slope intercept equation of the line below
1 answer:
Answer:
y = 2x - 3
Step-by-step explanation:
Step 1: Remember the equation
The slope intercept form is y = mx + b where m is the slope and b is the y-intercept
Step 2: Solve
We can see the y-intercept(where the line crosses the y axis) is at y = -3
We know slope is so we can see for every 1 square it moves right it moves 2 up so the slope would be
or 2
Plug what we know into the equation
y=2x-3
Step 3: Therefore Statement
Therefore the equation of the line shown below is y = 2x - 3

So here are a couple expressions when a value changes by percentage (p = percentage in decimal form and m = original value):
- When <em>decrease</em>: (1 - p)m
- When <em>increase</em>: (1 + p)m
So firstly, the $80 share dropped by 15%. Since this is a <em>decrease</em>, follow the appropriate expression:
<em>On Tuesday, the share went from $80 to $68</em>
Next, on Wednesday the share increased by $7. With this, just add $68 and 7.
<em>On Wednesday, the share went from $68 to $75</em>
Lastly, on Thursday the share increased by 12%. Since this is an <em>increase</em>, follow the appropriate expression:
<u>The final price of the share is $84.</u>
